Title: Switching power supply
Inventor: CHO HISANORI
IPC: H02M3/335
Filed: 2000-03-09
Abstract: PROBLEM TO BE SOLVED: To prevent the phenomenon of biased magnetization in a switching power supply including a transformer is connected to a switching circuit having intervals of positive and negative applied voltages. SOLUTION: The switching operation for a switching circuit according to a change of an input/output condition is controlled for every switching cycle or for its integral multiple, so the applied time of positive and negative voltage to the transformer is made the same in the constitution. When a modification for the control operation, such as a change of a voltage application term to the transformer, is required because of some reason like a variation of input/ output condition during the one switching cycle, the necessary modification is not carried out halfway the switching cycle and carried out just at the finish of the switching cycle or when a term of integral multiple of the switching cycle is finished. As a result, the applied time of positive and negative on the transformer is made the same under control, and the phenomenon of biased magnetization can be prevented.
